[0004] 2. Background of the Related Art

[0005] Generally video presenting systems include notebook computers,monitors, TV receivers, and the like. Referring to FIG. 1, for anexample, a notebook computer is provided with a body 10 havinginput-output-operation devices built-in therein, and a system housing 30having an LCD 20 and fitted to the body by a hinge part 31 projectingfrom a lower end of the system housing 30, and, though not shown, alower part of the monitor, or the TV receiver, is projected to someextent for fitting a control parts.

[0006] Though not shown, the LCD in the system housing 30 is, as knownin the art, provided with a flat display module. The flat display moduleincluding at least a back light part for emitting light by a lamp, aliquid crystal panel part (or display part) in front of the back lightpart for presenting a picture or video by utilizing the light receivedfrom the back light part. In addition, the notebook computer systemhousing 30 includes a frame for supporting edges of the flat displaymodule which maintains a required gap between the back light part andthe LCD panel part and a case for putting the display module and theframe together. A picture or video is reproduced by using molecularmovement of the liquid crystal in the liquid display panel part to allowpreselected light to be displayed.

[0007] A related art structure for mounting an inverter in an LCD willbe explained, with reference to the foregoing description.

[0008] Referring to FIG. 2, an inverter 21 for receiving utility power,converting the utility power to power required for the lamp, andsupplying the power to the lamp (not shown) in the LCD 20, may be fittedto a rear case of the LCD 20, or, though not shown, on an inside surfaceof the system housing 30.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

[0024] Reference will now be made in detail to the illustratedembodiments of the present invention, examples of which are illustratedin the accompanying drawings. Parts of the present invention similar tothe related art will be given the same reference symbols.

[0025] Referring to FIGS. 3A and 3B, the structure for mounting aninverter in an LCD 20 in which the inverter 21 is connected to a lamp ina display module for supplying a required power to the lamp is shown. Acase 22 for fixing the display module in accordance with a firstpreferred embodiment of the present invention includes a bracket 40fitted to a bottom surface of outside of the case 22 for fixing theinverter 21 to the bracket.

[0026] Referring to FIG. 3B, the bracket 40 includes a case part 41parallel to the bottom surface of the case 22 and an inverter part 42parallel to a front surface of the case 22. In one embodiment theinverter part 42 is positioned at a center of the case part 41 forpreventing the inverter 21 fitted to the inverter part 42 of the bracketfrom extending to the front or rear surface of the case 22 therebypreventing the LCD 20 from being made thicker due to the position of theinverter 21. For example, as the foregoing structure permits fitting theinverter 21 in a space of the hinge part 31 of the system housing 30, asshown in FIG. 1, the system housing can be made thinner. Accordingly, animproved system is shown wherein the system housing space of a notebookcomputer and the like are minimized.

[0027] In another embodiment, there may be more than one bracket 40 forsupporting the inverter at both ends. As shown in detail in FIG. 4A, afirst bracket 140 for supporting one end of the inverter 21 and a secondbracket for supporting the other end of the inverter 21 may be provided.

[0028] The mounting of the inverter 21 on the first, and second brackets140, and 240 will be explained with reference to FIGS. 4B, and 4C. FIG.4B illustrated a cross-section of the first bracket along section lineII-II′ of FIG. 4A., i.e. the right bracket, as shown. FIG. 4Cillustrates a cross-section of the second bracket, along section lineIII-III′ of FIG. 4A, i.e. the left bracket, as shown.

[0029] Referring to FIG. 4B, there is a guide projection 142 a extendingfrom the inverter part 142 of the first bracket and a guide hole 21 a atone end of the inverter 21 for inserting the guide projection therein.As shown in FIG. 4C, there are screw hole 242 a in the inverter part 242of the second bracket, and a coupling hole 21 b at the other end of theinverter 21. Accordingly, the guide hole 21 a in the inverter 21 isinserted in the guide projection 142 a from the first bracket 140 andthe coupling hole 21 b in the inverter 21 is screw fastened at the screwhole 242 a in the second bracket 240. At the end, the use of twobrackets 140 and 240 improves a supporting force to the inverter 21, andease of manufacture because one end of the inverter is inserted in thefirst bracket 140, and the other end of the inverter is screw fastenedat the second bracket 240.

[0030] In another embodiment, not shown, one end of the bracket 40, 140,or 240 and the bottom surface of outside of the case 22 may be coupledin a variety of methods, for example, by a projection from one end ofthe bracket and a hole corresponding to the projection in the case forinserting the projection in the hole and punching the inserted part orby welding or double faced tape, or by any other appropriate method.

[0031] As previously discussed these structures for mounting an inverterin an LCD of the present invention has at least the followingadvantages.

[0032] First, the LCD or the system housing can be made thinner.

[0033] Second, the case of a metal enhances a ground effect.

[0034] Third, all the effects mentioned in the detailed description ofthe present invention are included.

[0035] It will be apparent to those skilled in the art that variousmodifications and variations can be made in the structure for mountingan inverter in an LCD of the present invention without departing fromthe spirit or scope of the invention.
